摘要

采用基于gan的固态功率放大器的发射功率为30dbm，基于gaas的接收器噪声为3db，工作在71- 76ghz e波段的无线通信链路，实现了飞机与地面站之间数据传输速率高达9.8 Gbit/s的数据传输。在离地面1000米的高度飞行，距离接收器5到12公里，一架微型飞机将有效载荷安装在其机翼上。高定向链路由机载发射机中的39.7 dBi增益卡塞格伦抛物面天线和地面终端中的48.7 dBi基于gps的天线跟踪卡塞格伦天线组成。采用QPSK、8-PSK和16-QAM调制，建立了数据速率高达9.8 Gbit/s的稳定数据链路。

High System Gain E-Band Link in a Wideband Aircraft-to-Ground Data Transmission

A wireless communication link operating in E-band at 71-76 GHz with 30 dBm of transmit power from a GaN-based solid-state power amplifier and a 3-dB noise Figure of its GaAs-based receiver is employed in a data transmission with up to 9.8 Gbit/s data rate between a plane and a ground station. Flying at a height of 1000 m above ground and at distances between 5 and 12 km from the receiver, a microlight aircraft hosts the payload mounted to its wing. The highly directional link is formed by a 39.7 dBi gain Cassegrain parabolic antenna in the plane-mounted transmitter, and a 48.7 dBi Cassegrain antenna with GPS-based antenna tracking in the ground terminal. Stable data links were established with up to 9.8 Gbit/s data rate employing QPSK, 8-PSK and 16-QAM modulation.
